You are asked to establish a chassis cluster between two branch SRX Series devices. You must
ensure that no single point of failure exists.
What would prevent a single point of failure?
A.
dual data plane links
B.
redundant routing tables
C.
redundant cluster IDs
D.
dual control plane links

Using Dual Data Links
You can connect two fabric links between each device in a cluster, which provides a
redundant fabric link between the members of a cluster. Having two fabric links helps to avoid a possible single point offailure.When you use dualfabric links, the runtime objects (RTOs) and probes are sent on one link, and the fabric-forwarded and flow-forwarded packets are sent on the other link. If one fabric link fails, the other fabric link handles the RTOs and probes, as well as data forwarding. The system selects the physical interface with the lowest slot, PIC, or port number on each node for the RTOs and probes.
